My room is not "that" big. It's about 3.8x5.5m and I have to put my stereo at the short wall and play down the length of the room.I think the 2 Pi will be perfect, and there is no way I could afford any of the biggger designs, not right now. Gotta love Motorola/CTS for making these great cheap KSN-1038 tweeters :)
